I'm able to compress my v2 applicaton successfully. When I go through the application in testing I've found that some functions no longer exist. I've searched through the production.js and I can find calls to the function, but I can't find the definition of the function itself. It seems to me that in compressing the application there is also some level of optimization, as it were, that is adjusting variable names and the like. In this case it is also adjusting the name of a function, which is clearly not allowable. Is there any way to tune either the compress.js or env.js to avoid this?

One of the affected functions comes from a plugin called fullcalendar.js. The affected function is defined as: function setYMD(date, y, m, d).
